Welcome to the SDO Heliophysics Event Knowledgebase Wiki

This wiki supports development and use of the [http://www.lmsal.com/helio-informatics/hpkb/ HEK] software system for use by [http:hmi.stanford.edu HMI] and [http://aia.lmsal.com AIA] instruments on the Solar Dynamics Observatory (SDO) mission. Intended readers are regular users of SDO data or HEK softwar and developers of HEK software.

This is a work in progress. So Be warned!

Overview

Data collected by the AIA instrument be used to generate a variety of data products. A schematic of these and the steps in generating them is displayed here: attachment:AIA_highleveldataproductsp2.pdf. These products are the result of analysis and automated processing in the Lockheed Martin Solar and Astrophysics Laboratory's Level 2 system, attachment:SDOEventSystem.tiff. A draft for the types of events, data expected to be required to find them, possible detection methods, etc are show here: attachment:AIA_highleveldataproductsp3.pdf. Similarly, higher level products we expect to generate are summarized here: attachment:AIA_highleveldataproductsp4.pdf. More information is available here: attachment:AIAEventOverview.pdf.

Components

Registries

This is for materials on the Heliophysics Event Registry (HER, aka [http://www.lmsal.com/helio-informatics/hpkb/ HPKB]), Heliophysics Coverage Registry (HCR, see [http://sot.lmsal.com/sot-data LMSAL Hinode Data Center] for prototype) and the [http://www.lmsal.com/hpkb/pod Movie Registry].

Protocols & Standards

For the components of HEK to work, we have adopted certain protocols and standards. These will be documented here. Currently these are the Event Schema, Solarsoft and REST-style webservices.

Event Schema

HEK has adopted an enhanced form of the [http://ivoa.net/internal/IVOA/IvoaVOEvent/VOEvent_v1.1.html VOEvent] standard. In addition to some minor changes to better support heliophysical events, the HEK is developing a schema for classifying and describing features and events.
